I'm looking for ideas as to why this apparent misalignment should be and how it can be overcome. |
Hi Jeff. If you look up "astrobaby newtonian collimation" she shows by diagram (bottom of page) that what you are seeing is offset which happens in a fast newt. It's normal and I see this in my f5 newt.
